【摘要】：核電站汽輪機(jī)汽封系統(tǒng)的蒸汽泄漏量對(duì)電廠經(jīng)濟(jì)性有重要影響,采用數(shù)值求解方法,用有限體積法對(duì)控制方程進(jìn)行離散,并求解湍流模型的封閉方程組,分析了核電廠汽輪機(jī)上不同形式側(cè)齒汽封的流動(dòng)特性和泄漏情況。結(jié)果表明:在不同的進(jìn)口壓力下,單低齒側(cè)齒汽封的泄漏量低于雙低齒側(cè)齒汽封的泄漏量,有底齒的雙低齒側(cè)齒汽封和單低齒側(cè)齒汽封的泄漏量都略高于沒有底齒的。為優(yōu)化核電廠二回路汽封系統(tǒng)提供了理論參考。
[Abstract]:The steam leakage of steam seal system of nuclear power plant steam turbine has an important influence on the economy of power plant. The control equations are discretized by numerical method and finite volume method, and the closed equations of turbulent model are solved. The flow characteristics and leakage of different side teeth seal on nuclear power plant steam turbine are analyzed. The results show that under different inlet pressures, the leakage rate of single low tooth side tooth seal is lower than that of double low tooth side tooth seal, and the leakage rate of double low tooth side seal and single low tooth side tooth seal with bottom tooth is slightly higher than that of single low tooth side tooth seal. It provides a theoretical reference for optimizing the secondary loop steam seal system of nuclear power plant.
